摘要: 分子筛的吸附量与很多因素有关,文中就空塔气速、热边界条件、真空再生时间3个因素对分子筛吸附量的影响进行了实验研究,结果表明:实验范围内的空塔气速对吸附总量基本上没有影响,但是空塔气速对单位时间吸附量影响比较大;与自然对流情况相比,吸附床外部的绝热措施可以使吸附量提高95% 左右;真空再生时间对吸附量影响比较大,并以5h为宜.

Abstract:

The adsorption capacity of molecular sieves is related to many factors.Th is paper experimentally investi-gates the influences of superficial velocity,the thermal boundary conditions and the vacuum desorption time on the adsorption capacity.The results show that:(1)the superficial velocity basically does not affect the total adsorption capacity in the range of the experiment but somewhat greatly afects the adsorption capacity in a unit of time, (2)
compared with that in natural convection condition.the adsorption capacity would increase by 95% with the heat-insulating measures outside the adsorbent bed,and(3)the adsorption capacity is somewhat greatly affected by the vacuum desorption time,with a desirable time period of 5 h.

Key words: adsorption bed, molecular sieve, adsorption capacity, process condition
